tarmac UNITED 'sirArgs PATENT OFFICE.

goljgll'whom it may] concern Be it known that l, HENRY PRAoK, a citizen of the United States, residing at Ottawa, county of Lasalle,'and State of Illinois, have invented certain new and useful. Improvements in Cooling Devices for Trolley Wheels, of which the following is a specification. I My invention relates to 'improvements .in cooling devices for trolley wheels, that is to devices designed for use in connection with trolley wheels to serve as a means of maintaining the latter cool when in operation.

The object of my invention is the pro-' duction of a device of this character which will be of simple construction and efiicient in operation.

Other objects will appear hereinafter.

\Vith these objects in view, my invention consists in the cooler characterized as above mentioned and in certain details of conslruction and arrangements of'parts, all as will be hereinatter more fully described and particularly pointed out in the appended claims.

My invention will be best understood by reference to .the accompanying drawing. forming a part ot this specification and in which,

Figure l is a side elevation of a trolley pole and wheel to which is applied the cooling device embodying my invention, and, Fig. '2 is an enlarged, fragmentary sectional view of the eonstructionshown in Fig. 1,

g The preferred form of my construction as illustrated in the drawing comprises a trolley pole 1 which is formed in two parts, the

' upper part beingtubulan- Mounted at the upper end of the up er pole l is a trolley wheel 2 which may ti preferred design, said trolley wheel being so mounted however that the periphery-thereof i is disposed in direct alinement'withthe assage through the upper pole part an in close proximity with theupper extremity thereof. The pole parts are connected by means of a pipe coupling Arranged at the lower end of the pole 1 is a funnel member 4 sofirrranged that the expanded end thereof is directed forwardly.

The rearward contracted end of said funnel is in threaded connection with a. nipple" 5 formed upon the coupling-3, the arrangementbeing such, as will be observetihthat a direct communication is established between e of any ordinary or HENRY rnacx, or ocr'rawa, I'LLINOlSi coomive DEVrOIl-FOR recruit-WHEELS Specification of Letters Patent. Patented May 28, 1912, Application filed August 26, 1311., Serial No. 646,256.

A cooling device of the construction set.

forth is durable and economical the arrangement thereof upon the trolley pole'in no way affecting the free movement of thelatter or the free operation of the trolley wheel mounted thereon. Further, the deviee is of high efficiency in-usc and may be manufactured at. a very low cost.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, the same is capable of variation and modification without departing from the" spirit of the invention. I therefore do not wish to be limited to the precise details of construction setforth, but wish to avail myself of such variations or modifications as fall within th scope of the appended claims. "Having described my invention ,what I claim as new and desire to secure by Letters Patent is:

1. In a cooler for trolley wheels, the combination of a tubular pole; a trolley wheel mounted upon the upper end of said pole in direct alinement with the passage through said pole; and a forwardly QPPl'llflg tunnel communicating at its contracted end with said passage, substantially as described.

2. In a cooler for-trolley wheelmthe combination of a tubular pole; av trolley wheel mounted on the upper end of said pole in direct alinement with the passage through said pole; and a forwardly opening tunnel the lower end of the passage through the: upper pole part and the rearward end of the the forward bination of a tubular pole; a trolley'wheel- .mounted on the upper end of said pole in dircct'alinement with the passagethrough said pole; and a forwardlyopening funnel mounted upon said. pnle and having its rearward, c 'i'ntracted end threaded into said sage, substantiall as described.

s. In a cooler or trolley Wheels,,the combination of a twopart po1e,' the upper part being tubular; a tnolley wheel mounted upon the upper end of saidpoleindirect alinement with the passage through said upper pole part; a coupling connecting the adjacent ends of said pole parts; and a forwardly 0 ening funnel having its rearward contmcteg end connected with said coupling pole and in communication with said-pasindirect communication with the lower end of the passage through said upper pole part, substantially as described. v

In testimony whereof I have slgned my 16 name to this specification in the presence of two subscribing witnesses. i
